Most internet dating services charge its customers anywhere from $30 to $50 a month. I'm currently a member of a 100% free service, and I don't get a single e-mail in my inbox (except from ONE person, with whom things just didn't work out).
Not that I can't afford it, but why should I pay someone for the POSSIBILITY of meeting the love of my life that is just as improbable as all other walks of life I've taken? What would I be paying for? Why would I be paying them for their services without a garuntee of results or product?
